Rubidium nitrate is an inorganic compound with the formula RbNO3. This alkali metal nitrate salt is a white hygroscopic solid that is highly soluble in water.

Properties

[edit]

In a flame test, RbNO3 gives a mauve/light purple colour.

Solubility of rubidium nitrate in water

Production

[edit]

RbNO3 can be prepared either by dissolving rubidium metal, its hydroxide or carbonate in nitric acid.

RbOH + HNO3 → RbNO3 + H2O
Rb2CO3 + 2 HNO3 → 2 RbNO3 + CO2 + H2O
2 Rb + 2 HNO3 → 2 RbNO3 + H2

Uses

[edit]

Rubidium compounds have very few applications.[1] Like caesium nitrate, it is used in infrared radiation optics. It is also used as a raw material for preparation of other rubidium compounds and rubidium metal, for manufacture of catalysts and in scintillation counters.
